STRAIN INSULATOR CHAIN FiledJan. 27, 1931 Patented ug. 22, 1933 Henri Benit, Paris, France Y Application January 27, 1931, SerialY No. 511,565, and in Germany -January 28, 1930 1 claim. (o1. 173-318) The chains .of insulators usually employed for nately unite the upper portions and the lower portions of these insulators and that the elements oi the chain are insulators of the insulating stem type. with caps at both extremities.

Fig. 1 shows one embodiment of the invention. Fig. 2 represents in sectional elevation one ele-` ment of the chain. y .20V Fig. 3 represents a plan-view of an element of v the chain. f Y 1 Theinsulators a arejoined together by means of rigid bridge-pieces b, coupling alternately the lower caps and the upper caps. Inthe embodinient shown these bridge-pieces are given a T cross-section so as to prevent deformationA by bending or torsion. Their extremities are provided with circular seatings which fit the extremities of the caps to which they are iixed by means of screws.

The chainof four elements represented thus of adjacent insulators.

constitute a rigid whole capable of pivoting onlyA about the axis y of the end. coupling which is articulated on the cross-arm of the pole not shown on the drawing, the opposite end coupling being .'connected'to the wire orrcable of the line. 60 The insulators can thus be provided with oil cups c, pettcoats d protecting the oil'a'gains't weather effects. Y

The deviceforniing the object of this invention has the advantageof permitting the provision of` oil cups on horizontalanohorage chains with any type of insulator=support, or suspension insulator, on condition that these present a sufficiently high resistance.

Having now particularly described and ascer-v tained the nature of my said invention and in what manner the same is to beperformed, I declare that what I claim is: Y J

Strain,A insulator chain for horizontal traction,

comprising Yvertical-axis insulators having oil 75, Y `lledl cups the axis of ,symmetryof which coincides with that ,ofthe insulators, said oups creating a horizontalleakage pathfor the said insulators at the oil surface, andY connecting mem- Vbersrigidly'securing the insulators together, said connecting members being substantially rectilinear, disposed in parallel relation tothe axis of the insulator chain and connecting alternatively the upperv extremities and the lower extremities' ,Y
